I need to drill a hole in the center of the edge of a board about 1/2" thick. Looking for a shop made solution. The challenges:
Measuring and marking within a few thou'
Hard spots in the grain push the center punch off the mark - It's oak
Hard spots push the drill bit off the punch mark
Drill press tends to flex just enough to throw off a clamped setup, especially with a wide board
Not so easy to clamp a drilling guide to the workpiece
